Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a display board for a signboard, particularly a display board for a signboard having a mirror surface part and a transparent part.

BACKGROUND OF THE INVENTION In general, display boards for signboards are required to have light transmittance and also have the property that the light source cannot be seen from the outside. Conventionally, as a display board for such a signboard, for example, a milky white synthetic resin board is provided with a metal vapor deposition layer, and a patterned synthetic resin board has a mirror surface area made of the metal vapor deposition layer and other transparent areas. is used.

However, conventional signboard display boards have a metal vapor deposited layer directly on the surface of a milky white synthetic resin board, so it is difficult to display transparent characters, figures, symbols, etc. for advertising on this display board. In this case, the metal vapor deposited layer on the part representing the characters, etc. must be removed by etching, which poses a problem in that the work is extremely troublesome. In addition, when providing a metal vapor deposition layer on the surface of a milky white synthetic resin board, a protective film is placed in advance on the area where characters, etc. are to be displayed, and after the metal is vapor deposited, the protective film is peeled off to display the characters, etc. Although it is possible to form a transparent portion, since the characters and the like vary depending on each signboard, such a task is extremely troublesome, and of course is not actually done. In addition, milky white synthetic resin boards are made by blending the required amount of white inorganic filler into a transparent synthetic resin material, but display boards for signboards have varying thicknesses depending on the size of the signboard, etc. However, it was troublesome that milky white synthetic resin plates of various thicknesses had to be manufactured in advance and a metal vapor deposited layer had to be applied to each of them. Furthermore, if the amount of inorganic filler blended is constant, the cloudiness of a milky-white synthetic resin board increases as the thickness increases. It is necessary to change the blending amount of the inorganic filler depending on the thickness of the material, which makes the production of milky-white synthetic resin boards extremely troublesome and time-consuming. There was a problem that I couldn't do it.

Purpose of the invention This invention solves the above-mentioned problems and provides a mirror surface and a transparent part that can be very easily provided with translucent characters for advertising, and that can be manufactured very easily and inexpensively. An object of the present invention is to provide a signboard display board having a light section.

Structure of the invention The signboard display board according to this invention includes a base layer made of a synthetic resin film, a metal vapor deposition layer that is attached to one side of the base layer and has a mirror surface, and a transparent metal deposition layer provided on the base layer so as to cover the metal vapor deposition layer. Consisting of a backing material with an adhesive layer, a transparent plate to which this backing material is bonded to one side, and a film or plate that is light-transparent and has a high degree of haze and is bonded to the transparent plate. A character member having a desired shape, and a notch of approximately the same size as the character member is provided in the back material, and the character member is arranged in the transparent plate portion corresponding to the notch. be.

Embodiment Next, an embodiment of this invention will be described based on the drawings.

Note that in this specification, character members include all members constituting characters, figures, symbols, etc. for advertising.

In FIGS. 1 to 3 showing a first embodiment of this invention, a signboard display board 1 according to this invention includes a back material A having a mirror surface and a transparent plate to which the back material A is bonded to one side. B, and a character member C, which is bonded to the transparent plate B and is made of a film that is transparent to light and has a high degree of haze.

The backing material A is a base layer 2 made of a translucent synthetic resin film having light transmittance and high cloudiness.
and an intermediate layer 3 made of a flat transparent synthetic resin film bonded to the base layer 2 via an adhesive layer 6.
and a metal vapor deposited layer 4 which is attached to the intermediate layer 3 with a required light transmission gap 7 and has a mirror surface.
and an adhesive layer 8 provided on the intermediate layer 3 with a metal vapor deposited layer. Such a back material A has a predetermined pattern formed by a mirror surface portion made of the metal vapor deposited layer 4 and a transparent portion made of the light transmission gap 7.

In this invention, the backing material A is
A cutout 10 having the same shape as the character member C and having a slightly larger opening is provided, and the character member C is joined to the surface of the transparent plate B portion corresponding to the cutout 10, and is further joined to the transparent plate B of the back material A. Notch 1 on the opposite side
A rectangular backing piece D made of a light-transmissive film with a high degree of haze is bonded to cover the whole area. In addition, the character member C is arranged in a state that it is offset to one side with respect to the notch 10 having a slightly larger size.

As shown in FIG. 1, the signboard display board 1 has the following features:
For example, it is attached to a required wall 11 of a building via a rectangular frame 12, and a light source 13 such as a fluorescent lamp is arranged inside the display board 1. When light is irradiated from the light source 13, the required light rays are transmitted through the notch 10 to the character member C and the backing piece D, and the characters etc. appear in relief. In this case, since the character member C is arranged to be biased to one side with respect to the notch 10, the characters etc. appear more three-dimensionally. Further, the required light rays are irradiated to the outside from the light transmission gap 7 of the back material A, and a predetermined pattern appears. Of course, the light source 13 cannot be seen from the outside.

In the above, it is preferable to use a polyester film to which an inorganic filler is added, for example, as the film constituting the base layer 2 of the backing material A. In particular, it is preferable to use a polyester film in which at least 70% by weight of its constituent components is polyethylene terephthalate. Inorganic fillers usually have a white color and include oxides such as magnesium oxide, aluminum oxide, silicon dioxide, titanium dioxide, etc., and inorganic salts such as calcium carbonate, calcium sulfate, barium sulfate, etc. may be used alone or in combination of two or more. The average particle size of the filler is, for example, 2 to 20 microns. The amount of filler added is, for example, 0.1
~5% by weight.

A synthetic resin film to which such an inorganic filler is added has a milky white color, is translucent, and has light transmittance. The haze of this film, expressed as a percentage of the diffuse transmittance and the total transmittance, is, for example, 94 to 96%.

The surface of the base layer 2 has many irregularities and is rough, so even if a metal vapor deposition layer is directly formed thereon, it will not become a mirror surface. Therefore, this base layer 2
An intermediate layer 3 made of a flat transparent film is bonded to the intermediate layer 3 through an adhesive layer 6, and a metal vapor deposited layer 4 is provided on the surface of the intermediate layer 3. Since the surface of the intermediate layer 3 is smooth, the metal vapor deposited layer 4 has a mirror surface. The metal vapor deposited layer 4 is formed by forming the intermediate layer 3 by, for example, a vacuum vapor deposition method.
formed on the surface of Examples of metals used here include aluminum, silver, zinc, copper, and tin. In order to provide a light-transmitting part, that is, a light-transmitting gap 7 in this metal vapor deposited layer 4, first cover the surface of the part where the metal vapor deposited layer 4 is to be left with a transparent protective layer 9 made of a synthetic resin coating film, etc. When the surface is etched, a portion of the metal vapor deposited layer 4 covered with the transparent protective layer 9 remains, and other portions of the metal vapor deposit layer 4 are scraped off to form a light transmission gap 7 there. A predetermined pattern is formed on the surface of the intermediate layer 3 by a mirror surface portion made of the metal vapor deposited layer 4 and a transparent portion made of the light transmission gap 7.

Here, as the transparent film constituting the intermediate layer 3, it is preferable to use, for example, a polyester film in terms of heat resistance, dimensional stability, and weather resistance. As the adhesive constituting the adhesive layer 6, it is preferable to use a polyester adhesive in order to firmly bond the intermediate layer 3 to the base layer 2. Of course, other customary transparent adhesives may also be used, and it is also possible to use so-called adhesives.

Note that if the base layer 2 made of a translucent film has a flat surface with no unevenness, the intermediate layer 3 and the adhesive layer 6 can be omitted.

As the transparent adhesive layer 8, it is preferable to use, for example, an acrylic adhesive from the viewpoints of adhesiveness, weather resistance, and transparency. Other transparent adhesives or adhesives can also be used.

The transparent plate B is made of, for example, a synthetic resin plate such as acrylic resin, vinyl chloride resin, or polycarbonate resin. Further, the transparent plate B may be constituted by a glass plate. Such a transparent plate B has a thickness of, for example, 1.0 to 5.0 mm, and has the required strength to be used as a display board for a signboard. Further, the transparent plate B may be colored.

As the character member C, one made of a synthetic resin plate having light transmittance and high cloudiness is used. The character member C has the shape of a predetermined character, figure, symbol, etc. for advertising, and is colored appropriately. Note that the character member C may also be made of a colored glass plate or a translucent film.

The backing piece D is made of a synthetic resin film that is transparent to light and has a high degree of haze.

FIG. 4 shows a second embodiment of this invention. Here, the difference from the first embodiment is that the back material A has a notch 1 of the same shape and size as the character member C.
0 is provided, and the character member C is joined to the surface of the transparent plate B so as to correspond exactly to the notch 10. Therefore, the backing piece D as in the first embodiment is unnecessary. In addition, character member C
may be joined to the back surface of the transparent plate B while being fitted into the notch 10, as shown in FIG.

FIG. 6 shows a third embodiment of this invention. Here, the difference from the first embodiment is that the back material A is provided with a notch 10 that is slightly larger than the character member C, and the character member C is formed on the surface of the transparent plate B by cutting out the notch 10. The backing piece D is a translucent synthetic resin plate that is transparent to light and has a high degree of cloudiness. When such a signboard display board 1 is irradiated with light from the light source 13 inside, a border created by the required light rays passing through the backing piece D appears around the characters etc. represented by the character member C.

FIG. 7 shows a modification of the third embodiment, in which a translucent synthetic resin film having light transmittance and high cloudiness is used as the character member C, and this character member C is cut. It is fitted into the central part of the notch 10 and joined to the back surface of the transparent plate B.

In the above embodiment, a required light transmission gap 7 is provided in the metal vapor deposited layer 4 of the back material A, so that a predetermined pattern appears on the entire signboard display board 1 when irradiated with light. There is, but display board 1
may not form such a pattern. In that case, a metal vapor deposition layer 4 is provided on the entire surface of the base layer 2 of the backing material A, and a notch 10 approximately equal to the character member C is provided at a required portion of the backing material A.
Therefore, in this case, a transparent or opaque synthetic resin film may be used as the base layer 2 of the backing material A.

Effects of the invention This invention is based on the above, and in order to display the required translucent characters etc. on the signboard display board 1 having a mirror surface,
All that is required is to provide a notch 10 approximately equal to the character member C on the back material A, and then join the character member C to the front or back surface of the transparent plate B in a manner that corresponds to the notch 10, making the work extremely simple. Yes, signboard display board 1
can be manufactured extremely easily and inexpensively. When light is irradiated from the light source 13, the characters and the like formed by the character member C appear shiningly, and the light source 13 is not visible from the outside. In addition, the mirror surface made of the metal vapor deposited layer 4 does not allow light to pass through, and moreover, the surface of this mirror surface reflects people approaching it and surrounding objects, resulting in a very novel decorative effect. It is something.
